Specification of Letters Patent.

Patented Apr. 6, 1915.

To all whom it may concern:

Be it known that I, MARTIN RooKs'rED, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Torches, of which the following is a full, clear, and exact specification.

My invention is concerned with torches for starting the generation of the vapors from hydrocarbon oils for incandescent lamps, etc. As is well known to those skilled in the art, the generator of an incandescent hydrocarbon lamp must be raised to a high temperature by outside heat before it is hot enough to vaporize the oil and keep up its own temperature by the heat derived from burning the vapor it has itself generated and my invention is designed to produce a simple torch that may be clipped in or filled with alcohol, and lighted, to furnish the desired extraneous heat to the generator, and which will, when so lighted, at once furnish a steady and even flame from the time it is lighted until the charge of alcohol is burned when the generator will have been heated to the proper temperature.

To illustrate my invention, I annex hereto a sheet of drawings, in which the same reference characters are used to designate identical parts in all the figures, of Which,-

Figure 1 is a perspective View of a torch embodying my invention; Fig. 2 is a central longitudinal section; and Fig. 3 is a transverse section through the torch on an enlarged scale.

The torch comprises a trough a, which is preferably constructed of thin sheet metal, and which is generally rectangular in its outline, although its corners may be rounded off, as shown, if desired. The trough will preferably be provided with some suitable form of a handle, such for instance as the small rod 5, which may pass through an ear 0 extending up from the end of the trough, and which may conveniently be secured in place by washers d and 0, through which it passes, and to which it may be secured by riveting or otherwise upsetting the end of the rod constituting the handle.

Within the trough, I place a screen f, which preferably consists of thin sheet metal perforated, and which is preferably of a substantially inverted U-shape in cross-section, as seen in Fig. 3, the substantially U-shaped central portion being provided at its edges with ends 9 extending therefrom substantially at right angles so as to fill the bottom of the trough and hold the screen in place. Within the screen, I place a filling of asbestos fiber h, which will become saturated with alcohol if the torch is dipped in a bottle or other receptacle filled with the same. Or the trough may be held horizontally and the alcohol poured into the trough, if desired, when it will be soaked up by the asbestos. When thus charged with alcohol, the torch is put in place beneath the generator and lighted, and with the construction shown, immediately there is a steady blue flame rising to the desired height, and continuing at practically the same height until the alcohol is entirely burnt out, when the generator will be found to have been raised to the proper temperature so that the controlling valve can be opened and the burner ignited.

While I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of some modification, and that I do not desire to be limited in the interpreta tion of the following claims except as may be necessitated by the state of the prior art.

What I claim as new, and desire to secure by Letters Patent of the United States, is:

1. In a torch, the combination with a trough generally rectangular in its cross sec tion, of a perforated metallic screen therein, of a generally inverted U-shape in the same cross section, placed in the bottom of the trough, and a filling of loose asbestos fiber for the screen.

2. In a torch, the combination with a trough, generally rectangular in its cross section, of a perforated metallic screen therein,

' trough, and having its edges turned subof a generally inverted U-sha-pe in the same my hand and aflixed my seal, this 22nd day cross section, placed in the bottom of the of May, A. D. 1913.

MARTIN ROCKSTED.

stantially at right angles to the body thereof and extending to the sides of the trough, and a filling of loose asbestos fiber for the screen.

In witness whereof, I have hereunto set copies of this patent may be obtained for five cents each, by addressing the Commissioner oi. Petents,
